I have owned an EMM Labs CDSA player since 2007 which performs flawlessly and is very enjoyable. However the company has replaced the original Philips transport with a German model which is supposed to be more robust and sound better. I am tempted to have my player 'upgraded' but am hesitant since most of the comments I have read are vague or ambivalent about the improvement to be expected from the new transport. In addition, the modification is quite expensve, and I wonder how much difference a transport can make in the reproduction of a CD. Currently I am working on the old adage 'If it ain't broke don't fix it,' but would appreciate any comments from anyone who has made the change of transports on the CDSA.
